Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to an etching positioning device. Background Art

[0002] Etching is a technique that uses chemical reactions or physical impact to remove part of a material. Etching technology can be divided into two categories: wet etching and dry etching.

[0003] In the process of etching plate-like materials such as filter meshes, a positioning fixture is usually required to clamp and fix the material. The corrosive agent reacts chemically with the surface of the material, causing the surface of the material to be corroded to form the desired structure or pattern.

[0004] The existing etching positioning fixture has cumbersome clamping operation steps and cannot guarantee the stability of the material. When too much force is applied, the fixture is likely to damage the material. Moreover, the fixture cannot move after clamping the material, and more corrosive agents cannot quickly contact the material, resulting in a slower corrosion rate and time-consuming and labor-intensive process. Therefore, it is necessary to provide an etching positioning device to solve the above problems. Utility Model Content
